modifying the wash wipe sequence

Hi all,

Does any one knew if there is a way to modify the wash wipe sequence on the Fox or any VCDS long codes for the Fox that would change the way the wash wipe function on my Fox works.

Currently it's wipers move and are nearly back parked again BEFORE the water sprays. This has is the only thing that annoys me about the Fox and is responsible for the grazing on the windscreen as a result.

Id like to change it to the other way around so it sprays the wash fluid first then sends the wipers across.

Any thoughts and info on how this timing is managed are much appreciated!

I'm not sure on your Fox but my Golf you pull up the wiper stalk and it sprays water as well as operating the wipers. I haven't looked in VCDS to see if there is an option to change this.

Do you have access to VCDS?

You're also burning the midnight oil I see :P

It does spray and wipe like any other car as normal. But it does nearly a complete back and forth of the wipers before any water lands on the screen. Dragging all the muck across the screen before adding wash fluid. This I believe is responsible for the grazing of the glass that's been building up over the last couple of years. Other cars and vans I've owned or driven tend to spray water as the wipers start to move or just before.

A buddy of mine had got VCDS and he said find the info and we shall go and do it. But I've never played with it and have no idea what the craic with it or how it works other than he told me to "find the long code" for what I want to tinker with.

Hope that means more to you than me!

I highly doubt that it's possible to change this behaviour through coding / vcds. It will be hard coded into the wiper control unit.

On mine, water first and plenty of it, then wipers.
On my wife's previous Nissan Note, lots of water then wipers.
On my faithful Accord, both at the same time which wasn't great.
On all previous cars wipers first and then eventually water which annoyed me intensely.

Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.

Mine washes then wipes. It's a 2006 Fox 1.2. I wouldn't have thought the programming would have changed. Perhaps it's the one-way valve that prevents the fluid flowing back to the reservoir that's failed. I don't know if there's a one-way valve in the washer nozzles - the nozzles are very easy to change because they unclip - I've never seen that on a car before - must be a VW thing. If the one-way valve is at the reservoir end I've not had reason to fiddle in that area so no idea I'm afraid.

What you could do to check - operate the wash-wipe by holding the switch position until you get a decent flow out of the nozzles. Pause a moment. Then do it again. If it now washes before wiping but wipes before washing if you leave it overnight - bingo - it's the non-return valve!
